To a stirred suspension Magnesium chloride (71.0 gm, 0.745 mole) and Para-formaldehyde (33.6 gm, 1.12 mole) in Tetrahydrofuran (200 ml), Triethylamine (104 ml, 0.745 mole) was added at room temperature and stirred for 30 minutes. To the reaction mixture; the solution of Indan-4-ol (50 gm, 0.373) in Tetrahydrofuran (100 ml) was added at room temperature and heated to 70-75° C. for 6 hours. To the reaction mixture, 2N Hydrochloric acid (600 ml) was added and extracted with Ethylacetate (2×500 ml). The Ethylacetate layer was washed with water (300 ml), dried over Sodium sulphate and further it was distilled under vacuum to give viscous oil (52.0 gm) which becomes solid upon keeping.
